为检验普鲁斯特效应提取是否存在气味辨别确定的决策阶段，在实验一和实验二中分别以气味、气味词和不同辨认度的气味为线索，设置干扰任务，考察自传体记忆基于气味线索回忆的提取时间差异。实验一发现，语词标签和气味不一致条件，自传体记忆提取时间出现干扰效应，而气味一致条件未出现。实验二发现，难、易辨认度气味均有干扰效应。表明普鲁斯特效应提取存在气味辨别确定的决策阶段，它是气味本身和气味辨别确定所激活的气味语义表征促进了自传体记忆提取的“双加工”机制。

This study inspects the difference of the retrieval time of autobiographical memory. Two experiments are designed to reveal that whether existing a decision process of odor identification in the proust effect. In the two experiments, subjects were presented with odors, or labels of the odors’ names, or odors of different identification levels. We find that there is interference effect in conditions of label cue with an incongruent odor cue, but not in conditions of a label cue with a congruent odor cue. And we find that there are interference effects in both conditions whereas difficult or easy levels of odor identifications in experiment 2. These suggest that the decision process of odor identification exists in the retrieval of autobiographical memory when evoked by odor. It is showed that the retrieval of autobiographical memory based on odor cuing is a kind of dual-process mechanism, in which the odor itself and the odor identification promote the autobiographical memory retrieval process together.
